i checked it on the source of the video on youtube of tron uprising new episode with flashback on it it's PURE: a new character appears on the sneek peak his name was dyson we was once a good friend to tron his circuitry color was formerly white.

until he betrayed him and serve loyalty to clu (after the beginning of clu betrayed flynn and tron) and his current circuitry color is red and he wears the mask of the black guard.

and now he's back and tron wants revenge on dyson and tron remains beck behind and tron is going after him alone to finish what he started and i saw tron scars is getting much worse.

and i saw clu on the sneak peek riding his light cycle and in tron legacy during flynn's escape i saw tron snatch one of the guards identity disc so in tron: uprising tron will grab dyson's disc (possibly) instead of snatching one of the guards.

so the tv show is non-canon and i don't think tron is transforming to rinzler in the 8th episode we got ten episodes to go but we're gonna find out.
